PIPE HANGER.

Application filed July 25, 1921. YSerial No. 487,414.

' The invention relatesito improvements in pipe hangers. l

One of the objects of the invention is, generally, to improve pipehangers.

b Another object is to provide an adjustablev fitting. having one ormore indicating apertures. or longitudinally extending slots,thru whichto visually ascertain the position of the threaded rod or pipeadjustable therein, l with respect to the fitting, operable vfor thepurpose of raising or lowering either side of the pipe .hangerstructure.

Another object is to provide an improved housing or receptacle withinwhich the fitting is insertable and by which it is supported.

-Another object isto provide a ttingwhich may be adjustably attached toboth ends of a vertical pipe supporting rod or pipe.

Other, further and more specific objects of the invention will becomereadilyapparent, to persons skilled in the art, from a consideration ofthe following description when taken in conjunction with the drawings,wherein Fig. 1 is an end elevation of the hanger showing the lit-tingreceptacle orY insert support embedded inthe cement overhead wall orfloor.

Fig. 2 is an enlarged cross section of the insert' support orhousingwith the .fitting therein.

Fig. 3 is a transverse section taken on line 3 3 ofFig. 2.

tion at the lower end of the vertical rod as it appears in Fig. 3.

Fig. 5 is an enlarged transverse section taken on line 5 5 of Fig. 4.

Fig. 6is a modified form kof the lsupport and receptacle, or plate.

Fig. 7 is an end elevation of another modication of said support.

Fig. 8 is a'r front elevation of Fig. 7.

Fig. 9 shows, in end elevation, substantially the same bracket orfitting support as that shown in Figs. 7 and 3, but shows different pipehangers..

Fig. 10 is a front elevation of the structure shown in Fig. 9.

In all the views the saine reference characters are employed to indicatesimilar parts. In adjusting pipe hangers, in which a pair of rods orpipes are employed for supporting l one or more fluid conducting pipesit often becomes necessary to adjust the altitude of Fig. t is anelevation, showing part in sec-.

thelatter pipes at intermediate points where Vit is supported byparticular hangers in order that the inclination of the conducting pipemay be uniform, that entrained water resultg from condensation of thesteam, or other liquid, may iiow in a desired direction and to avoidpockets or abnorn'ially low portions in the pipe. Such adjustment isfrequently required' as a result of settling of a building, or the like,after the pipes conveying the fluid or liquid have been installed, andthere.- fore, to bepractical, every one of the Pipe hangers mustindividually be capable of adn justme'nt so that the supported pipe maybe raised or lowered, as occasion may require.

lNhere two vert-ical pipes, or rods of a hanger, are cross connected bya transverse member for supporting one or more. iuid conveying pipes itis quite essential that each of the vertical rods may independently beadjusted, and it is furthermore very" desirf able' that the location ofthe end of the rod,A in the fitting required for the adjustment, should`at all times be seen or ascertained, so that the ent-ire hanger may notinadvertently be disconnected and permit the conveying .f

pipe to fall vorto descend to any degree from its normal intendedpositionof support.

It is quite convenient, also, to provide a f pipe hanger fitting whichmay be used for verticaladjustment of the side supporting -rods of thehanger without the necessity of disarranging any of the parts thereofand l.without removing the device as an active support forthe-pipe.

1n the drawings 15 is the improved universal fitting, or threadedsleeve, for engagenientI with the vertical side rods orpipes 16 of thepipe hanger. The fitting 15 is interiorly threaded for the rod or pipe16, and is preferably provided on its low-er end with a polygonalterminal 17, by which it may be bodily rotated by application of awrench. The fitting 15 is provided with a cylindrical part 18 and arounded headl 19, spherically tapered as at '20. The cylindrical portion18 is provided with'- one or more longitudinally extending slots 21 inthe bore, thru which the side rod 16 may bel seen. There. may be twosuch slots, 21, opposite' each other, so that the" end 22 of thevertical` rod 16 becomes clearly visible. /Jhen the ends 22 of the rodspass beyond the boundary of the slot 21, in either direction, theoperator then knows that the rod 16 has been inserted in the fitting 15,as far as may be,

or it has been Withdrawn therefrom as far as safety will permit. rlhefitting is adaptable for location on the top end of the rod 16, and alsothe bottom end of the rod 16 as more clearly shown in Fig. 4, in Whichevent a check nut 24 may be used to more rigidly secure the fitting 15to the rod 16. `When the fitting 15 is employed at the loiver end of therod 16, the fitting 25, more clearly shown and described in my copendingapplication Serial No. 462,873 filed April 20, 1921, for supporting atransverse rod or pipe 26, may be made to surround the lower end of thefitting, and the head 19 Will prevent fitting 25 from leaving thefitting 15. ln this particular' case the members 2? and 28 of the titing 25 are secured together by the transverse clamping bolt 29. rfhetingl consists of the two clamping members 2T and 28, held together bythe bolt 2% which is inserted between the fitting 15 and the end of thetransverse pipe or rod 26, as more clearly slioivn in Fig. 4. rlhefitting 15 may be rotated by engagement of a Wrench with the angularportion 17 thereof to raise or lower the transverse support 26. rlhe nut24 will prevent rotation of thc rod 16 vvhile the fitting 15 is being`rotated for shortening or lengthening the effective lineal dimensions ofeither of the rods 16.

After the adjustment has been made at the upper end of the rod 16, bymeans of tl i i) fitting 15, the lovver end of the rod and the fitting15 may be correspondingly adjusted so as to still further increase ordecrease the effective length of tie structure. By providing a hanger ofthis character the fitting 15 is adaptable for use at both the top andbottom end of the rod 16, thus a very extended range of adjustment maybe had and the expense of the structure decreased by the duplication ofthe parts in the respective positions.

Another feature of the invention consists in the means for supportingthe fitting 15 and the pendant rod 16 which consists of an insert orhousing 8O for insertion in a cement Wall 31. The housing is providedwith Knock-out closures 82 which may be knocked from the housing and apipe 33 passed therethru for providing additional support for thehousing in the cement structure rllhe lower Wall 34 of the housing isslotted and spherically curved to receive the curved head 19 of thefitting 15 to render the fitting self-adjustable, so that it Will alwaysbe in vertical alignment and curved at its top surface to facilitate itsintroduction in a holder, as at 85, to admit the cylindrical part 18,but to prevent the head 19 from passing therethru. At the end of theslotthere is an opening 36 that permits the entrance of thehead 19 onlyWhen the fitting is inclined from the vertical, as shoivn by dottedlines in Fig. 2, but which Will not permit the iitting 15 to pass thruthe slot when it is in vertical position,-so that so long` as there issuspended Weight attached to the fitting 15 it cannot leave the housing30.

The knock-out closures 32 prevent entrance of the cement into thehousing 8() when the rod 38 is not used. Nails 39 may be passed thru thehousing to hold it te the form upon which the cement Wall 81 is to bemade.

`instead of using the insert or housing 8() when the hanger is to besuspended from an ordinary ceiling, the plate 87 may be einployed whichis provided with the same slot ?5 and Which may be secured to an over--ead Wall or ceiling by bolts that may pass vliru the openings 38. lnFigs. 7, 8, 9 and.

10, l have shown the plate-37 in the form of a bracket when the hangingmembers are to be supported from a side Wall 40. rlhe inner loiver end41 may be slotted, as at 42, to pro vide for some lateral adjustment andthe upper end 48 is provided with a perforation 44 thru rvuich a bolt orsore-W may be passed to hold the bracket to the vvall.

An angularly disposed member 44 is connected to the outer end of theplate 37 as at 45 and to the upper terminal end 48.V ln.

Figs. 7 and 8 the rods 16 suspended from the fittings 15 have fittings25 fastened there to. 1n Figs. 9 and 10 hangers 26 are suspended fromthe rods 16.

The fitting may be held in any sort of support, that engages the head ofthe fitting and which permits its rotation and permits automaticadjustment thereof to align itself vertically.

Having described my invention what l claim as new and desire to secureby Let-ters Patent, is

Pipe hangers comprising a pair of vertical members having threaded ends,a sleeve threaded on each of said ends and having slots therein, apolygonal portion and a swivel head, housings adapted to receive theheads of the upper sleeves for swiveling movement, clamping membersadapted to be clamped around the loiver sleeves and to be supported bythe heads for relative swiveling movement and a transverse member joining said clamping members and adapted to support aA plurality ofpipes.

in testimony whereof l hereunto subscribe my name.
